2 + 2 = 3: Making Ternary Phases through a Binary Approach

New work from the Kauzlarich group in collaboration with NASA Jet Propulsion Laboratory looks to unveil the mysteries of solid-state reactions. The investigation into the formation of Yb₁₄MSb₁₁ (M = Al, Mn, Mg), a high efficiency thermoelectric material, from the elements and binaries revealed a pathway for the direct formation of high purity complex ternary phases in balanced stoichiometric reactions utilizing binary precursors.

2+2=3 Making Ternary Phases through a Binary Approach

The formation of Yb₁₄MnSb₁₁ directly from a mixture of YbSb, MnSb, and YbH. This phase exhibits high thermoelectric performance at high temperatures and is under consideration for the next generation of radioisotope thermoelectric generator for deep space exploration.
